Abstract (en)

[origin: EP4140574A1] The present invention relates to an aerosol generation device, which includes an accommodating assembly, a gas passage tube (20), and a heating assembly (50). The accommodating assembly includes a fixing tube (10) configured for fixing an aerosol-forming substrate (100). The fixing tube includes a hollow and two-end-penetrating structure, of which the two ends are respectively formed with a first opening (111) and a second opening (112) in communication with the first opening (111). The gas passage tube (20) is sleeved around the outer circumference of the fixing tube (10) and includes a support wall (211) facing the second opening (112). The heating assembly (50) inserts through the support wall (211) to extend from the second opening (112) into the aerosol-forming substrate (100) in the fixing tube (10). The aerosol generation device further includes a gas flow channel that sequentially conveys external air between the fixing tube (10) and the gas passage tube (20) to reach the support wall (211) to then move from the second opening (112) into the aerosol-forming substrate (100) in the fixing tube (10)..
